There is also on Ammas.com where you can not only ask but also answer the queries, if you know the answers. You can also try that out. You can earn too by placing adsense code in the site and by answering.

If you can answer queries about products which you can link IRC to, you can do that and give the links for that. You'll get cash credits and points also.Regards,Latha JayaprakashIndia Review Channel
